Library for building an evented socket server.
The socket component provides a more usable interface for a socket-layer
server or client based on the EventLoop and Stream components.
The server can listen on a port and will emit a connection event whenever a
client connects.
The connection is a readable and writable stream. It can be used in a server or in a client context.
Here is a server that closes the connection if you send it anything.
$loop = React\EventLoop\Factory::create();
$socket = new React\Socket\Server($loop);
$socket->on('connection', function ($conn) {
$conn->write("Hello there!\n");
$conn->write("Welcome to this amazing server!\n");
$conn->write("Here's a tip: don't say anything.\n");
$conn->on('data', function ($data) use ($conn) {
$conn->close();
});
});
$socket->listen(1337);
$loop->run();You can change the host the socket is listening on through a second parameter provided to the listen method:
$socket->listen(1337, '192.168.0.1');Here's a client that outputs the output of said server and then attempts to send it a string.
$loop = React\EventLoop\Factory::create();
$client = stream_socket_client('tcp://127.0.0.1:1337');
$conn = new React\Socket\Connection($client, $loop);
$conn->pipe(new React\Stream\Stream(STDOUT, $loop));
$conn->write("Hello World!\n");
$loop->run();
